The invention relates to an environment monitoring system () for a vehicle (), wherein the environment monitoring system () comprises: at least two distance sensors (---) for detecting distance by measuring the propagation time of detection signals, wherein the distance sensors (---) are each designed as a transmitting unit and receiving unit for the detection signal and, in a direct operating mode, emit detection signals, receive reflected components of the detection signals emitted by the distance sensors; and emit active measurement signals according thereto; and a control device (), which receives the measurement signals of the distance sensors (---) and determines an object distance (s) of detected objects (). According to the invention, at least one distance sensor (---) additionally can be operated in an indirect operating mode in order to detect a detection signal emitted by another distance sensor (---) and reflected by the object () and in order to generate an indirect measurement signal. 1313.
